Abstract
Abstract The present invention relates to a process for dyeing or printing a flat form textile substrate which comprises applying onto the substrate an aqueous dyeing or printing liquor having a viscosity below 500 cps and comprising a synthetic thickener precursor which contains carboxylic acid groups in free acid form, the substrate having been pretreated by depositing thereon a solution of a basic compound, the dyeing or printing liquor being converted on contact with the pretreated substrate into a gel having a viscosity from 3,000 to 60,000 cps.
